Sorry, I don't believe they make negative shims as others have already
pointed out. The bars are already bigger than the stem.

Oops, yes, that's correct. Your best bet, then, will be to find a set
of 25.4mm drop bars to fit the mtb stem. Although it would be
possible to resize the bar clamp to fit the larger diameter, this is a
tricky process when the clamp must be honed or machined with a fixed
gap retained to ensure that the clamping is successful afterwards.
It's been a good many years since I had access to the type of hone
that would do this easily, and I'd be hesitant to trust the task to
someone unfamiliar with the requirements. Accordingly, the more
rational approach is to match the sizes of the components.

In the "old days" my friend, Bicycle Bob, put a 26.4 Cinelli bar
through a 25.4 SR road stem by prying the clamp apart a little. He rode
it many hard miles without a problem. Your mileage may vary.
